Main squeeze: Alex Rodriguez gives his girlfriend Cameron Diaz and affectionate pat on the bottom during a fun day out yesterday
They have always been fiercely private about their relationship, keeping it out of the public eye as much as possible.
But it seems as if Alex Rodriguez may have given up on hiding his true feelings for Cameron Diaz.
The New York Yankees slugger was spotted giving his girlfriend of a year an affectionate pat on the bottom yesterday as the couple boarded a boat cruise with friends in Miami, Florida.

As the couple walked side-by-side along the jetty towards the waiting boat, Alex, 35, who is also known as A-Rod, reached behind her and gave her left cheek a squeeze.
Cameron was displaying her long lean legs in a pair of tiny white shorts which she paired with a pretty pink linen shirt and gold aviator sunglasses.
Later she stripped off her clothes and showed off her toned and taut stomach in a tiny white string bikini as she soaked up the sun aboard the boat.

A-Rod was casually dressed in blue shorts and a white T-shirt which he accessorised with a blue baseball cap.
Later in the day the couple were spotted having a low-key evening hitting up a local Whole Foods grocery store where they picked up several bags of food before heading back to A-Rod's star island home.
The pair were falsely rumoured to have split earlier this year, but their relationship is clearly stronger than ever.
